Fuelled up yesterday at Shell here in N.B. and regular was 1.42 but the 91 octane was lower at 1.54 than yours.
Weird how gas prices are sitting so differently between regular and supreme grades, that is a big spread there in your area ?
We don't have 93 here.
But with air miles and caa cards there is a 10 cents savings on the 91, so finally a bonus as I run that in most of my stuff.
Highway 7, Vaughan Ontario was the Shell station location. I was up that way for work this week. Left @6:30 am, got in Moncton before midnight after a 1.5 hr unplanned stop in Edmundston for technical support for one of our techs. I was making good time until then!
